We carry a full line of transmission rebuild kits, filter and brake bands for the BTR line of transmissions. The BTR are usually found in Asia, Australia and Europe and used by different vehicle manufactures. Below is partial list of the different trans model and vehicles it can be found in.

The A604 family of transmission is used in a wide variety of vehicles and for many years proving to be one of Chryslers' most successful 4 speed automatic front wheel drive transmission. Some of the vehicles equipped with this unit are: Acclaim, the Caravan mini vans, Dynasty, the Voyager mini vans and a few others.

The A606 was used in vehicles like the Intrepid and New Yorker. The 42RLE is the rear wheel drive version of the A606 and can be found in the Durango and Dakota Pickup.

Here is a list of the different valve bodies available for these units:

The S531 is a standard or manual transmission manufactured by ZF and used primarily by BMW.

We will discuss the different kits and the component of each that are available for this unit. The numbers listed are the most common. We do carry parts other than the ones listed and for other gearboxes not listed. Since there is a long list of transmission part numbers, that is the number on the tag on the transmission itself, not all will be listed here. The best way to order kits and parts is to have the transmission tag information ready when ordering.

Sometimes its unavoidable and you will need to replace a drum, or cylinder as it is known in ZF world, for your ZF automatic transmission. Probably the most common replaced drum in the ZF5HP18 are the "D" and "F" drums. The D drum functions as the center support.

We will list the different drums, part numbers and most common transmission codes used with the part number. The assemblies usually comes with the drum, o-ring, cup spring, oil dam, snap ring, piston, spring clutch disc, steels, frictions and end plate.

Why the title you ask? Well its quite simple. When originally released by ZF the 6HP26 solenoids where only going to be available as a complete unit with the valve body known as the Mechatronic.

The solenoid pictures to the right is a blue capped one and is part number 0501 213 959. If you need a solenoid for your 6HP26 please let us know the color of the cap, the location in the valve body and the color of the ones on either side.

Please do not hesitate to comment if you have any info as this would help our blog readers.

These parts are very important to any electronically controlled transmission and should be inspected carefully when conducting a rebuild or when dropping the valve body. Pay particular attention the Governor Pressure Solenoid and Sensor. When replacing one you should always replace the other especially in this unit.
